Slide down a slope and
jump over two rows of spikes. You slide down into an area with columns and a
deadly water pool. Climb the ladder side of the south-east column. Then shimmy
to the left and pull up into a small room. Use the floor lever and you hear a
door open. Exit this room and climb back down to the ground. Climb the ladder
side of the north-west column. Then shimmy to the left and pull up into a small
room. Enter the room and a skeleton rises out of the floor. Pick up the shotgun
and the Horseman's Gem and go back to the room entrance.

Exit this room and climb
back down to the ground. Climb the ladder side of the south-west column. Then
shimmy to the left and pull up into the opening. Use the Horseman's gem to open
the door. Stand jump over the spikes and pick up a Horseman's Gem. Stand jump
back to the entrance and notice that the north door is open. Exit this room and
climb back down to the ground. Climb the ladder side of the north-east column. Then
shimmy to the left and pull up into a small room. Pick up two red shotgun
shells and beetles start to attack. Use the Horseman's Gem in the receptacle
and you hear a door open. Exit this room and get back to the ground. The large
doors to the north are open.

Enter the door and get a
flyby of the pit showing a skeleton and two mummies. Safety drop onto the
platform with the mummies. Then safety drop to the ground. Go north and stop just
before the picture tiles. Some of the picture tiles are deadly fire traps. Step
onto the right tile with a mountain picture. Go east to the pillar and then
turn north. Run straight north to the water fountain. That was a real trail and
error guess. Dive into the water and swim north. Pull up into the next room and
shoot the four skeletons into the water.

Step on the picture
tiles in the following order: south-west, north-east, south-east, north-west,
and finally the middle picture tile in front of the pool. An earthquake should
happen and you get a cut scene of the fountain area with the deadly floor. Swim
back there and follow the safe tiles back to the entrance, Go south and see
three openings into ice caves. All three ice caves contain a pool that all lead
to the same area. If you use the pool to the east side, you can pick up a small
medipack. You pull up into a room and get a short flyby of the central
platform. Give yourself full health and run and jump to the south side of the
platform. Spikes will pop up and take some health. The platform should rise
with you on it and go up into a chamber. If you jump to the north side of the
platform, the platform rises without you. There seems to be no end trigger so
just exit the game.
